| Abstract: | The rigid block joint element (RBJE) method is a numerical method to study a deformation and a movement of a rigid block system, and it may be used to study a limit equalization problem of the elastic plastic body. With a general program of the 3 D RBJE, this paper calculated the upper bound of the square base limit load on the center of the top surface of the square pillar. The result illustrates the RBJE method has a good precision and a wide suitability. |
